Patented Aug. 4, 1931 JOSEPH WILLIAM nnn'rznn on WARREN,

OHIO, ASSIGN'OR TO THE HELTZEL STEEL JFORM AND IRON COMPANY, OF WARREN, OHIO, A CORPORATION OF OHIO BELTING Application filed August '7,

The present invention relates to belting devices such as are used for belting or smoothing ofi' the surface of a concrete road under construction, it being a prevailing practice to use a belt which is reciprocated transversely across the road before the concrete has set. 1 i r The present invention has for an object the provision of a novel and improved frame for 1 holding a finishing belt, in order that the "belt may be conveniently manipulated.

Another object is the provision of an improved belting devicein the form of a bow, for holding the belt taut, and having provisions for adjustment. v

A further object is the provision of such a device having novel handles for conveniently manipulating the device.

A still further object is the provision of novel means for regulating the bowing of the bowbetween the ends of which the belt is stretched. a

"Still another object is the provision of a belting device of the character indicated which is of simple and inexpensive construction, being conveniently constructed from metal stock, and being convenient and eflicient in use. I

With the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation of the im proved belting device in use, showing the concrete road and side form rails in cross section.

Fig. 2 is an enlarged section on the line 22 of Fig. 1.

Figs. 3 and 4t are sectional details on the respective lines 33 and 1-4 of Fig. 2.

Figs. 5 and 6 are enlarged cross-sections on the respective lines 55 and 66 of Fig. 1.

The belt 10 is of leather, fahric or other 50 suitable flexible material, and is stretched be- DEVICE 1929. Serial No. 384,078.

tween the ends of a resilientbow 11 forming part of the belt frame. The bow is composed of the angle iron sections 12 which are overlapped at their adjacent terminals, in order that the frame may be shortened and lengthened. The an le iron sections are arranged with thein external angles disposed upwardly. Clamps 13 embrace the overlapping terminals of the sections 12 and have clamping screws 14: to seat within the internal angles of the sections, as seen in Fig. 5,.for clamping the sections together in the desired adjustment thereof. \Vhen the screws 1% are loosened, the sections 12 maybe slid relatively to one another to increase or decrease the length of the frame. I

' The opposite ends of the sections 12 are pressed together, as at 15, and are pivoted by bolts 16 between angle pieces 17 secured by bolts or rivets, or otherwise, on sheet metal yokes 18 that areIdisposed transversely across the ends of the bow 11. The 'yokes 18 have bearings 19 at their ends in which tubular spools 20 are mounted for rotation, and said spools have slots 21 between the bearings 19 to receive the terminals of the belt 10, inorder that theterminals of the belt may be wound on said spools within the yokes i18.

'Co'tter pins 22 are inserted through apertures in the bearings 19 and spools 20 for holding said spools against rotation whenth-e-belt is wound thereon, and the sp-oolsmay have suitable apertures to receive the pins 22 or other suitable securing elements.- The spools 20 project from one bearing 19 of each yoke and have apertures 23 for the reception of arod or other implement that is used for turning the spools. 'It is apparent that when the belt is wound on the spoolsthis will, in tightening the belt, thereby move the ends of thebow 11 toward one another so as to bow said bow into an arc of less radius.

The frame includes ahandle at each end, and each handle is composed of a pair of bars 24 secured togethe'r with a spacer 25 between the upper terminals-thereof, and a handle rod 26 extends through the upper end portionsiof said bars tobe conveniently grasped by the hands. The bars 24 have the diverging portions 27 above the yokes 18, with feet 28 secured by bolts 29 or otherwise on the yokes 18. The diverging portions 27 are disposed astride the ends of the bow 11 and pieces 17, as seen in Fig. 2.

Braces o0 connect the handles and bow. One end of each brace is pivoted by .means of a bolt or pin 31 between the bars 24 of the correspond ing handle, said bars having vertically spaced aperturesSQ to receive the bolt or pin 31. The other end of the brace is pivoted by means of a bolt or pin within the slotted lug u astanding from a clamp 35 embracing the bow 11 and having a set screw 36 to bind within the internal angle of the bow, as seenin Fig. 6.

lVhenthe set screws 36 are loosened the clamps may be adjusted longitudinally on the bow to adjust the angles of the handles. The braces 30 also transmit the strains from the handles to the bow 11 when the handles arenianipulated for reciprocating the device overthe concrete before it has set.

The frame may be constructed inexpensively from metal, and is light in weight. ihe frame also enables the belt to be conveniently reciprocated over the concrete and side rail forms, in the position as seen in Fig. 1. The bow 11, may be lengthened or shortened conveniently, and the handles may also be adjusted to different angles with reference to the bow and belt. The handles enable the operator or operators to stand erect when belting the road, without having to stoop over or kneel down. v This makes the present device more convenient to manipulate and also saves considerable time.

Having thus described the invention, what is claimed as new is v 1. A belting device comprising a bow, belt spools carried thereby at its opposite ends, and a belt connected to the spools.

. 2. A belting device comprising a frame having adjustably connected sections, and a belt connected to the end portions of the frame.

3. A belting device comprising a bow having adjustabl'y connected sections, and a belt connected to the end portions of the bow.

4. A belting device comprising a bow having adj ustahly connected sections, belt spools ('flllGCl by the bow at the opposite ends thereof and a belt connected to the spools.

5. A beltingdevice comprising an angle iron bow with its exterior angle disposed upwardly. and a belt connected to the end portions of the bow.

A belting device comprising a bow havangle iron sections overlapping one an other, clamping means embracing the overlapping portions of said sections, and a belt' connected to the opposite ends of said sections.

7. A belting device comprising a bow, transverse yokes conneted. to the opposite ends thereof and having-spaced bearings, belt 10. A belting device comprising a bow, a belt connected to the opposite end portions thereof, upwardly extending handles pivotally connected with the end portions of the bow, clamps adjustable on the bow, and

braces connecting said clamps and handles]- 11. A belting device comprising a. bow, yolres .pivotally connected with the ends of the bow, a belt connected to said yokes, upwardly extending handles secured on said yokes, and racing means connecting said handles and bow.

12. A belting device comprising a bow, yokes pivotally connected wlth the ends of the bow, spools mounted in said yokes, a belt connected to said spools to .be wound thereon, upwardly extending handles secured on said yokes, clamps adjustable on the bow, and braces connecting said handles and clamps.

In testimony whereof I hereunto aflizi my signature.
